mm/memcg: relocate mod_objcg_mlstate(), get_obj_stock() and put_obj_stock()
All the calls to mod_objcg_mlstate(), get_obj_stock() and put_obj_stock() are done by functions defined within the same "#ifdef CONFIG_MEMCG_KMEM" compilation block. When CONFIG_MEMCG_KMEM isn't defined, the following compilation warnings will be issued [1] and [2]. mm/memcontrol.c:785:20: warning: unused function 'mod_objcg_mlstate' mm/memcontrol.c:2113:33: warning: unused function 'get_obj_stock' Fix these warning by moving those functions to under the same CONFIG_MEMCG_KMEM compilation block. There is no functional change.
